This paper will explore the path from the field wear problem to the bench test solution. The perspective will be from that of the product designer who is experiencing a wear problem in the field. Attention will be given to extracting the necessary key information in the field problem to assist in the subsequent testing steps. A tribological code is developed to facilitate the transition from the field problem to the bench test.
The impact of the selection of contact geometry will be reviewed relative to the various test machines which are available. This is more complex today since there are many test machines and many of the test machines utilize adapters which permits a multitude of test geometries. Many special test variations have been developed over the years and these will be discussed to show the broad spectrum of testing opportunities which exists. Consideration of all the test parameters relative to accelerated tests will be reviewed.
The techniques of initial exploratory tests prior to starting the test program will be reviewed relative to the field problem and the proposed test conditions.
Interpretation of the test results will be explained for several test examples.
